Like the E3C246D4I, this is a reasonably affordable off-the-shelf
mini-ITX AST2500/Xeon motherboard with good potential as an OpenBMC
development platform. Booting the host requires a modicum of eSPI
support that's not yet in the mainline kernel, but most other basic
BMC functionality is available with this device-tree.

It does not look like you tested the DTS against bindings. Please run
`make dtbs_check W=1` (see
Documentation/devicetree/bindings/writing-schema.rst or
https://www.linaro.org/blog/tips-and-tricks-for-validating-devicetree-sources-with-the-devicetree-schema/
for instructions).


As with my spc621d8hm3 dts patch, I did run that and got no output, so if there are other specific problems please let me know what they are.


Whoops, and of course now I realize I also sent the first reply to this thread instead of the spc621d8hm3 one...
